Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing system executed on a computer having a graphic display function, and more particularly to a page-oriented document editing system for editing a document with a page as a basic unit.

[0002]

2. Description of the Related Art In a conventional document, pages are one-dimensionally continuous, and the conventional page-turning operation cannot efficiently find a target page when the number of pages is large.
In addition, it is often difficult to perform a cut-and-paste operation across multiple pages. As a method of collectively handling a large amount of documents, it is known as a book function of collectively handling a plurality of documents as one document. this is,
A document in which one-dimensional documents are arranged is handled as a virtual document, and is functionally limited to the operation of a one-dimensional document array.

As another document processing method, a method is known in which a logical structure for structuring a document into units such as chapters is introduced to enable structural editing. An example of SGML is known as a document structure based on a logical structure. SGML
For information on ISO Information Processing-Text
and office systems-Standard Generalized Markup
Language (SGML) ", ISO-8879 (published on October 15, 1986), describes detailed specifications as an international standard.

[0004]

As described above, in editing using a logical structure, when the amount of continuous text is large, the logical structure makes sense and an improvement in operability can be expected. However, there is a problem in that it is not suitable for improving the operability when the amount is small.

The present invention has been made in view of the above problems, and an object thereof is to provide a tribute-oriented document processing apparatus capable of operating a plurality of pages collectively and improving the efficiency of editing operation. It is to be.

[0006]

In order to achieve the above object, a page-oriented document processing apparatus according to the present invention sets a page which is a constituent element of a document at a node position of a two-dimensional tree structure, It is designed to incorporate tree structure operations into the page editing function.

[0007]

[Operation] By locating the page at the node of the tree structure,
Since the page has a hierarchical structure with elements as elements, it is possible to operate the page in a unit by operating the node of the upper node in the tree structure. By directly displaying this tree structure on the hierarchical menu and operating the page using the hierarchical menu, a plurality of pages can be collectively edited and the operability can be improved.

[0008]

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 shows a user interface of one embodiment of the present invention. A user interface is realized by using a page menu 1 for operating pages and an arbitrary number of in-page editing windows 2. The in-page edit window 2 can simultaneously display a required number on the screen as needed.
Here, the page menu 1 and the in-page edit window 2 are displayed on a graphic display on a workstation having a graphic display function. Further, the display of the menu itself and the display of the edit window are realized by a graphic display device and software for graphic display, but these display methods themselves are widely performed on general workstations and are well known in the art. Since it exists, its details are omitted.

FIG. 2 shows an example of a page menu for operating a page. The page menu is displayed on the screen independently of the in-page edit window for editing the data in the page. Display the page name on each line of the page menu. The user sets a page name when adding a page. Here, if the page name is not set, the page name is automatically added on the system side. Figure 3
An example in which the scroll icon 3 is displayed on the page menu is shown in FIG. When the number of pages in the document is too large to display all the page names in the menu, the scroll icon 3 is displayed to enable scrolling. The display of the icon itself is generally performed in a workstation having a graphic display function, and therefore its detailed description will be omitted.

FIG. 4 shows an example of hierarchical display of the page menu.
The page menu hierarchy takes an arbitrary number of levels. A plurality of pages can be collectively registered as a page group. The registered page group is displayed on the page menu in the same manner as a normal page menu, but a triangular icon 4 is displayed at the right end of the menu to identify the page group name. When this page group is selected, a list of pages registered in this page group is displayed as a submenu of the page menu. As with the upper page menu, the lower page menu also displays a scroll icon when the display size exceeds the display size, enabling scrolling.

FIG. 5 shows a diagram for moving pages by operating the page menu. An arbitrary page can be moved by selecting the page to be moved (range in the case of a plurality of pages) on the page menu and dragging it to the page of the move destination.
FIG. 6 described later shows an example in which the page “b” can be moved after the page “d” by docking the page “b” to the position “d” on the page menu.

FIG. 6 shows an example of grouping a plurality of pages. A plurality of pages are collectively defined as a page group. The grouped page group is named and registered at the current page level, and the pages (plurality) belonging to this page group are registered under this page group. The page or page group is registered in the page group. In the example of FIG. 6, "b, c,
The figure shows that three pages of "d" are collectively registered as a page group "grp-x".

In the above-mentioned example, an example in which existing pages are collectively registered as a page group is shown. However, it is also possible to register the page group first and then register the pages in the page group. is there. In this case, first select the position in the page menu where you want to add the page group, and then use the command "A
Run "ddGroup". This command adds a new page group after the selected page on the page menu.

FIG. 7 shows an example in which a page to be edited is selected on the page menu and an in-page edit window is displayed. Double-clicking the page group "grp-x" on the page menu will display a sub-page menu showing the contents of the page group. By double-clicking on the target page "sub-b" from among them, the edit window of the page "sub-b" is displayed. Similarly, when other edit windows are displayed, the in-page edit windows of a plurality of pages can be simultaneously displayed by double-clicking on the page menu.

Next, the document structures of the prior art and the present invention will be compared with reference to FIGS. 8 and 9. FIG. 8 shows a conventional document structure, and the document 5 has a structure in which pages 6 are arranged in a one-dimensional array. On the other hand, according to the present invention, a hierarchical relationship is set between pages, which is different from the conventional structure in which pages are one-dimensionally arranged. FIG. 9 is a diagram showing an embodiment of the structure of a document according to the present invention. As shown in FIG.
The document 5 has a document structure in which pages 6 are two-dimensionally connected. The portion corresponding to the node 7 on the hierarchical structure in FIG. 9 has a relationship corresponding to the above-mentioned page group. Below the node 7, an arbitrary number of pages 6 or the node 7 itself is set. Since it is possible to set node 7 under node 7,
The number of layers of the node 7 is not limited.

FIG. 10 shows the main components of the system.
The event processing unit (10) receives an event generated by a user operation such as a key input or a mouse operation, and passes the event to the page menu processing unit (20) or the in-page data editing processing unit (30). The page menu processing unit (20) interprets the received event and performs the operation intended by the user. Further, the page menu processing unit (20) updates the display content of the page menu displayed on the graphic display when the page menu display needs to be updated as a result of the user operation. Further, if the operation intended by the user is related to the in-page data edit processing section (30), the page menu processing section (20) generates a command and sends it to the in-page data edit processing section (30). The in-page data edit processing unit (30) is an event processing unit (10).
Event or page menu processing unit received from (20)
Process according to the command received from. The result of this processing is displayed in the in-page editing window on the graphic display by the in-page data editing processing unit (30). The data management unit (40) exchanges necessary data with the page menu processing unit (20) or the in-page data editing processing unit (30). The file management unit (50) performs a process of extracting a document file from the storage device or storing it as a file in the storage device according to an instruction from the data management unit (40).

Next, a processing flow according to the present invention will be described with reference to FIGS. FIG. 11 shows the overall processing flow of the page menu. In process 110, it is checked whether or not it is the initial display when the document is opened, and in the case of the initial display process, the initial display process is performed in process 120. In process 130,
It is checked whether or not a single click with the mouse has been performed in the page menu, and if it has been performed, the processing of processing 140 and thereafter is performed. In the process 140, it is checked whether or not the clicked place is within the scroll area, and if it is within the scroll area, the page scroll process 160 is executed. If the mouse click is outside the scroll area, the process 150 selects the menu item at the position clicked in process 150. In the process 170, it is checked whether or not a double click is made on the page menu,
If so, page open processing 180 is performed. In process 190, it is checked whether or not a page operation command is input, and in the case of command input, process 200 and subsequent steps are performed. In process 200, it is checked whether the input command is a page open instruction. In the case of the page open instruction, it is checked in step 220 whether the page instructed to open is selected by the item in the page menu, and if it is selected, the page open processing is performed in step 230. When it is determined in the process 200 that the process is not the page open process, in the process 210, the edit process in the page menu is performed.

Since the page open process and the page menu edit process are closely related to the understanding of the present invention, they will be described in more detail. FIG. 12 shows a detailed processing flow of the page open processing. In the determination process 310, it is determined whether the item to be opened is a page group. If it is a page group, the process 320 opens the page group. If it is not a page group, it is checked in the decision processing 330 whether or not the page is already displayed. If it is displayed, the edit window of the page is moved to the foreground of the screen in process 350. If it is not displayed, it is confirmed in the determination process 340 that the corresponding page exists. If the corresponding page does not exist, an error message indicating that the corresponding page does not exist is displayed in process 360. If the page exists, the edit window is generated in process 370. In the determination processing 380, it is determined whether window generation has succeeded. If the creation of the edit window fails, a window failure error is displayed. If the generation of the window is successful, the data of the corresponding page is displayed in the generated window.

FIG. 13 shows a detailed processing flow of page menu editing processing. The determination process 510, 520, 530, 540, 550 determines the command type. In the case of moving, the moving process is performed in process 515. In the case of copying, the copy process is performed in process 525. In the case of paste, paste processing is performed in process 535. In the case of deletion, the deletion process is performed in process 545. In the case of page grouping, step 555 performs page grouping processing.

In the moving process in process 515, the item to be moved is dragged while being selected on the page menu, so that the contents of the selected item are moved after the item at the position where the mouse is released. If the selected item is a page, the page is moved, and if it is a page group, the page group is moved. When multiple pages are selected, multiple pages are moved. The movement can be performed between layers when a plurality of layers are displayed on the page.

In the copy process in process 525, the contents of the item selected in the page menu are copied to the clipboard. The contents of the clipboard are saved until a new copy or cut is performed. If the item selected in the page menu is a page, the contents in page units are copied to the clipboard. If the item selected in the page menu is a page group, the page group is copied to the clipboard. When multiple pages are selected, the multiple pages are collectively copied to the clipboard.

In the paste process in process 535, the clipboard contents are inserted after the item selected in the page menu. The contents of the clipboard do not change. When the data in the clipboard is a page, the contents in page units are inserted. If it is a page group, a page group is inserted. When multiple pages are copied to the clipboard, the multiple pages are inserted together.

In the deletion process in process 545, the item selected in the page menu is deleted. When the item selected in the page menu is a page, it is deleted page by page. If the item selected in the page menu is a page group, the page group is deleted. When multiple pages are selected, multiple pages are deleted together. Processed in Figure 14
Details of the 555 are shown. In the page grouping process in process 555, a plurality of items selected on the page menu are registered as a page group. A new page group name is determined in process 555a. The name is determined by inquiring from the user, but if the user does not specify, a name that does not duplicate is automatically set. In process 555b, a page group is generated, the name determined in process 555a is assigned, and the page group is inserted at the same position as the selected item. In process 555c, the selected page group is moved into the newly generated page group. Finally, the page grouping process is performed by updating the page menu display by the process 555d.

By assigning a document to a node set on a two-dimensional tree structure like a page and handling it, a pseudo document having a two-dimensional structure can be realized across a plurality of documents. FIG. 15 shows an example of the document structure in that case. By setting the document and the page in the node of the tree structure without distinction, a document in which the document and the page are mixed can be configured. FIG.
The main components of the data management unit (40) are shown in FIG. The page menu processing interface unit 610 controls the interface with the page menu processing unit 20, and exchanges data with the page menu processing unit 20 via the interface. The in-page data edit processing interface unit 620 is a part that controls the interface with the in-page data edit processing unit 30, and exchanges data with the in-page data edit processing unit 30 via this.
The data management unit 630 is a unit that manages document data in a tree structure on the main memory of the workstation. The node data management unit 630a manages node data, the page data management unit 630b manages page data, and the document itself. A document data management unit 630c, which manages, is configured as a main element. The file management interface unit 640 is the file management unit 5
This is a part that controls the interface with 0, and exchanges data with the file management unit 50 via this.

When the user uses the page menu to add a page to a node, the data regarding the added page is recorded in the page data management unit 630b, and the updated result of the node data itself with the added page is the node data. It is recorded in the management unit 630a. When the document is registered as node data, the data related to the document is registered in the document data management unit 630c. Similarly, when a page is deleted from a node or a document is deleted, the change result is recorded in the node data management unit 630a, page data management unit 630b, and document data management unit 630c. In this way, the data of the document tree structure is managed.

[0026]

As can be understood from the above description, according to the page-oriented document processing apparatus of the present invention, a page which is a constituent element of a document is set at a node position of a two-dimensional tree structure,
Since the operation of the tree structure can be incorporated into the page editing function, it becomes possible to operate the page in a unit by operating the nodes on the hierarchical structure of the tree structure with the page as an element. Become. In addition, the tree structure is directly displayed on the hierarchical menu, and the page operation is performed using the tree structure, which has the effect of improving the editing operation of the organized pages.
